Thorikos occupies the coastal northeast of the Lavrion area of Attica, Greece. The ancient town comprised the double-peaked Velatouri hill, which has seen human activity since the Final Neolithic period and been the focus of archaeological research for more than 50 years. 0This publication serves as a guide to ancient Thorikos, a presentation of ongoing work and a preview of new undertakings. Growing out of a Belgian initiative in the 1960s, the Thorikos Project is today an international program with a wide range of contexts and assemblages under study. Here, members of the international team present themes of current interest and aspects of recent work in a multi-authored collection of texts intended for the general public as well as for specialists.
